Just moved into new construction. *Everything in the house seems to be

Anyway, my question is whether the contractor grade grass seed will

I doubt it. *Probably used a lot of rye to get quick growth. *I would

Agree 100%. Depending on where the OP is, I would wait until the end
of August. I need to fertilize (the phosphorous levels are through
the floor) but will wait at least another three weeks to apply. This
isn't a good time of year for grass.
